Jeff Layton 12965a190e filelock: allow lease_managers to dictate what qualifies as a conflict ... Requesting a delegation on a file from the userland fcntl() interface currently succeeds when there are conflicting opens present. This is because the lease handling code ignores conflicting opens for FL_LAYOUT and FL_DELEG leases. This was a hack put in place long ago, because nfsd already checks for conflicts in its own way. The kernel needs to perform this check for userland delegations the same way it is done for leases, however. Make this dependent on the lease_manager by adding a new ->lm_open_conflict() lease_manager operation and have generic_add_lease() call that instead of check_conflicting_open(). Morph check_conflicting_open() into a ->lm_open_conflict() op that is only called for userland leases/delegations. Set the ->lm_open_conflict() operations for nfsd to trivial functions that always return 0.
